Yeah, I didn't phrase that right.  I am looking to build a single large 
RAID array.  Speed in and out of the box will be bound by ethernet 
speeds; my concern is if the mobo can handle the traffic on the PCI 
bus.  The reason I ask is that I had a problem with a mobo that couldn't 
handle 6 drives - it would periodically 'collapse' and just start 
thrashing aimlessly.  I've also had problems with a mobo that couldn't 
handle ethernet + HD activity very well.

I can imagine that a couple of PCI-*x SATA cards plus 6 on-board SATA 
ports can cause quite a few interrupts internally.

So I'm looking for any suggestions for chipsets / brands /etc to 
use/stay away from, and so on.
